Hyperspectral radiometers, with a calibrated range of 350 - 800 nm and fully characterized cosine response, are designed to be mounted on real-time profilers, coastal and deep water buoys, autonomous underwater vehicles, research vessels and airplanes.

Based on the highly successful ac-9, the ac-spectra (ac-s) offers almost an order of magnitude increase in spectral resolution of in-situ absorption and beam attenuation. The 4 nm resolution allows for spectral "fingerprinting" and deconvolution analysis.
